Too everyone complaining about the Fizz Change.
Don't worry I promise you that they will revert back to his old w. They a reverted Lb and Rengar back because they weren't "fun" AKA they were balanced and weren't 1 shotting everyone.So trust me they will eventually deem the new fizz as "unfun" and revert him.
Riot wouldn't dare take the "fun" aka "balance" out of the new fizz W. They didn't with rengar or lb So don't worry.
Just be patient It'l happen. Only time they don't revert changes is when They are actually more broken than before.
That last sentence rings true.
